GAUGING AND PUNCHING DEVICE Filed Nov. 22, 1954 INVENTOR. AIFPEDJ W/E'D/GEE United States Patent GAUGING AND PUNCHING DEVICE Alfred J. Wiediger, Kent, Wash. Application November 22, 1954,.Serial No. 470,293

4 Claims. (Cl. 33-197) This invention relates to gauges and punching devices to aid carpenters and non-skilled workers in hanging doors.

A particular environment in which the present invention has greatest utility, is in the hanging of cabinet doors which are hingedly mounted by offset hinges. In this field, the door base is provided With a front panel which overhangs-the door base and the door hinges are hung on the back surface of the door base and the offset portions fit snugly against one edge portion of the door base and. thence under the overhanging portion of the front panel and thence are connected to an exposed hinge. Next in such field, the other leaf of the hinge is mounted on a door stile. This type of construction and field is such that it is difiicult to measure and define the exact position that the holes will take to provide for the desired alignment of the door hinges.

Whenever hinges are employed to hang a door, the hinge pins must be in vertical alignment and aligned to the dooror else the doors will not swing properly.

Thus;it is an object of my invention to provide a tool whichcan be readily employed and which will not only mark .but punch the desired openings for screws so that after the door is properly punched, it is only necessary to lay the hinge over the holes and then insert the screws in .place and the hinges will be properly secured to the door. Thereafter the door can .be inserted in the door opening and clearance allowed on the four marginal portions (if a rectangular door is employed) and the desired openings in the door stile can be readily marked and thereafter punched or drilled so that the screws can be screwed in place hanging the door hinge on the door stile- It is an object of my invention to provide a hinge markingand punching device which will provide the necessary precision and thus eliminate the heretofore necessary skill'in properly hanging a door hinge.

Otherrobjects and advantages of my invention will becomexapparent as the description of the same Proceeds andthe. invention will. be best understood from a consideration of the following detailed description, taken in. connection with the accompanying drawings forming a part-ofthe specification, with the understanding, howeverythat the invention is not to be limited to the exact details of construction shown and described since obvious modifications will occur to a person skilled in the art- Figure 1 is a perspective view of a device embodying my invention;

Fig. 7 is a fragmentary view partly in elevation and partly in section illustrating the hinge of Figs. 5 and 6 secured at its end portions respectively to a door and a door stile; and

Fig. 8 is a fragmentary enlarged view, with the parts shown in the same position as Fig. 2, and particularly illustrating the details and mode of operation of the preferred form of calks employed in my invention.

In the hanging of doors, and particularly cabinet doors, it is essential that the hinge pins be aligned or else two spaced apart hinges will not provide for proper swinging movement of the door. My invention is designed particularly to aid the carpenter, or non-skilled worker, in accurately and precisely hanging doors of the offset type.

Referring now to Figs. 4 to 7 of the drawings, an off-v set hinge is shown and the offset hinge comprises a door leaf portion numbered generally 10 and a stile leaf portion numbered generally 11. The said door leaf portion 10 comprises a flat portion 12, a right angular portion 13, and a portion 14 which is parallel to the flat portion 12. Thus the portion 14 is offset but parallel to the portion 12. The amount of offset or the height of the portion13 is commonly of an inch in standard offset hinges and at times is A of an inch. The stile portion 11 comprises a flat portion 15 and the portions 14 and 15 terminate with pin receiving recesses to provide a piano type hinge between the portions 10 and 11. The.

pin 16 may be of the removable type, or not, depending upon the particular make of the hinge. The flat portion 12 of the door leaf portion 10 is provided with a plurality of holes such as the three holes 17 which are typical and generally standard. Thus in my invention I have provided for gauging and punching means to provide three holes in a door and which holes will match and align with the openings 17 in the flat portion 12 ofv the door leaf portion 10. The openings of holes 18 in the stile leaf portion 11 are easily aligned with a stile. and the device of my invention does not contemplate.

punching holes in the door stile to align said. holes with the holes 18 in the stile leaf portion of the hinge as such holes can be readily punched or drilled or marked when a door carrying an offset is aligned with the door open ing in the cabinet.

As will appear in Fig. 4 of the drawings, it is standard practice to employ a door having a base portion 19 and a front portion 20 so there is a marginal recess of the portion 19 as respects the front portion 20 and the portions 13 and 14 of the hinge member will abut respectively a marginal portion of the door base 19 and the adjacent right angular portion of the door face 20. The door 1920 may thus be made of two pieces or the door may be grooved to provide from a single unit the portions 19 and 29.

When the door and hinges are in place, a plurality of screws 21 will project through the openings 17 and into the door base 19. Next the marginal portions 13 and 14- of the. door leaf portion 10 will abutthe marginal portions of the door as indicated in Fig. 7 of the drawings, and. then the stile leaf portion 15 will be secured to a door stile 22 and screws 23 will hold the stile leaf 15 against the door stile 22. With the hinge shown in Figs. 5 and 6 of the drawings, of course there will be two screws Patented Nov. 12, 1957 3 23 through the openings 18 in the stile leaf portion 11 of the offset hinge.

Now referring to the device of my invention which is designed to mark or gauge and punch a cabinet door such as the door 19--20, the said device comprises a baror elongated member 24. One end portion of the bar member 24 is provided with an elongated slot 25 and adjustable stop gauge 26 carries a squared or mating portion 27 which matches the marginal edge portions of the slot 25 so that the adjustable stop gauge 26 may move longitudinally of the slot 25 and without turning motion of the adjustable stop gauge 26. The mating portion 27 terminates in a threaded portion 28 and a thumb screw 29 threadedly engages the threaded portion 28 and upon tightening of the thumb screw 29, any longitudinal adjustment of the adjustable stop gauge 26 relative to the slot 25 may be maintained and with the gauge edge portion 38 normal to edge 39.

The other end portion of the bar member 24 is provided with a slot 30 which extends crosswise of the bar 24 or at right angles to the slot 25. An anvil member 31 has a striking face 32 which will normally be the outer face of said anvil 31. The inner or calk carrying face 33 carries three calks 34 and said calks 3d are preferably detachable. and such calks are provided with piercing points at one end portion and threaded portions at the other end portions. Thus said calks may be readily used and they can be threaded in appropriate openings in the anvil member 31 and with the calks projecting from the face 33. The pattern as to Spacing of the calks 34 is such that said calks will provide openings in a cabinet door 19--20 which openings are to receive screws 21 which project through the openings 17 in the door leaf portion of the offset hinge. The method of approximately aligning the openings in the door 19-40 will be described in connection with the mode of operation of the tool of my invention.

The bar 39 and the anvil 31 are interconnected by a thumb screw having a head 37, a pin guide portion 35 and a threaded portion 36. The threaded portion 36 threadedly engages matching threads in the anvil 31. When the thumb screw is tightened, the sleeve or pin guide portion 35 is mounted for sliding movement in the slot 30 and also for rotative movement relative to the bar member 24.

Preferably the pin 35 is offset toward the inner or calk carrying face 33 and closer to said face than it is to the striking face 32 of the anvil member 31. This permits the calks 34 to be moved above a door surface to be gauged and punched and with a minimum dimension of the bar member 24.

Referring now to Figs. 2 and 4 of the drawings, the door 19-29 is first prepared so that the marginal portion of the base 19 of the door is properly jointed to provide a true line so that the door may be hung properly. The edgeportion which is to carry the hinges is shown to the left in Fig. 4 of the drawings. Then the gauge and punching device of my invention is placed as shown either to the top or to the bottom of Fig. 4 of the drawings. Start ing with the position shown at the top of Fig. 4 of the drawings, the gauge surface 38 of the adjustable stop 26 engages with the end portion 4 of the door base 19. An adjustment has beenfirst made so that the relative height of the hinge to the door i9-20 is determined. This is accomplished by moving the adjustable stop gauge 26 longitudinally relative to the slot 25 and then securing any desired adjustment by tightening of the thumb screw 29. The gauge and punching device of my invention is placed with the gauge surface 39 of the bar member 24 adjacent and in contact with the surface 41 and the door base 19. The anvil member 31 has not been rotated in Fig. 4 over the showing in Fig. 1 so that the inner or calk carrying face 33 is directed toward the outer surface of the door base 19. The said anvil 31 can be I find that calks used for loggers boots are suitable moved relative to the bar member 24 in view of the crosswise slot 30 in the bar member 24. Thus the said anvil member 31 due to its connection with the bar member 24 may be moved toward and away from the door base 19 and at the same time it can be rotated so that the calks 34 will rest on the outer surface of the door base 19. In such position the outer or striking face 32 of the anvil member 31 may be struck with a suitable tool, as a hammer, and the calks 34 driven into the door base 19. The type of holes which will thus be driven are such that screws can be directly screwed or turned into place and this is accomplished after the hinge 1611 is inserted in place after the gauging and punching device has been removed. The holes in the door provided by the calks 34 are so aligned that the screws 21 may be inserted in the holes so provided and the hinge will automatically align itself in the appropriate and desired position.

In marking the lower side of the door, as the portion shown toward the bottom in Fig. 4 of the drawings, the device as it is shown towards the top may be picked up and turned to the position shown toward the bottom of Fig. 4 of the drawings and the anvil 31 will be rotated degrees. Again the device may be positioned in the proper place as will now be readily apparent, and then the striking face 32 of the anvil member 31 may be hit by an appropriate tool, as a hammer, and the desired three openings will be punched in the lower portion of the door base 19 and if the adjustment previously made for the adjustable stop 26 is maintained, then the spacing of the hinges at the top and the bottom of the doors will be mated vertically considered of the door. Crosswise considered of the door, of course the punchings will be mated in that each is determined by the bar 24.

Obviously from the foregoing detailed description, it will now be apparent that I have provided a gauging and punching device for hanging hinges and particularly hinges of the offset hinge type. It is to be understood that my invention is not to be limited to a device for merely hanging offset hinges, as other hinges having different patterns of holes may be readily hung by devices embodying my invention. Of course with a change of hinges, the pattern of the calks must be changed to mate the hinge hole pattern of a particular hinge. However, in any event, the hinge pins may be vertically aligned on any door, employing a device embodying my invention, and precision work results even though amateur door hangers are employed for a job.

The adjustability lengthwise of a slot of the adjustable stop gauge 26 permits the adjusting of hinges vertically of a door and permits the same spacing at the bottom as at the top of a door. of the bar member 24 permits crosswise positioning of the anvil relative to the door so that the pattern of holes provided by the calks 34 is such to positively mate with the pattern of holes on a hinge so that the appropriate hinge leaf can be hung by merely inserting screws in the openings in the door provided by the calks 34. If a hinge is to be hung intermediate a top and bottom hinge, then the adjustable stop gauge 26 may be removed and the mid-distance of a door determined. Then the device can be employed with the surface 39 engaging the surface 41 of a door and holes punched for hanging an intermediate hinge leaf. The removable feature of the adjustable stop gauge 26 thus functionally enters into the combination.

Due to the fact that the anvil 31 is rotatively connected with the bar member 24 and is movable crosswise thereof, the anvil member 31 may be struck with a hammer and the holes punched in a door and without any strain on the bar member 24. Obviously if the connection between the anvil member 31 and the bar member 24 is merely a rotative connection or is merely a crosswise sliding connection, the full benefits of my invention will not obtain.

Often doors are made of plywood With slash or of other grain so that the calks 34, if the same are perfect Similarly the gauge surface 39 I cones, would tend to move toward or away from the adjustable stop gauge 26. As is best illustrated in Fig. 8 of the drawings, I have determined that the calks 34 should have a greater incline on one surface adjacent the tip than on the other. Thus calks 34 may be cut away at a 45 angle such as illustrated by 34a with the incline toward the bar member 24 when the anvil 31 is in normal operating position. While the degree of inclination may vary, I prefer at least 35 and about 45 as this will permit the use of a tapered and pointed calks and at the same time on additional inclined surface on one side only to provide sufficient force tending to move the calks 34 in a direction away from the bar member 24 as they are driven into the base 19 of the door 1920. As the gauging surface 39 of the bar member 24 rests against the surface 41 of the door base 19 at the time a hammer is urged against the striking face 32 of the anvil member 31, then the tendency of moving the calks inwardly is resisted and hence the calks 34 are driven into a desired position in the base 19 of the door. For purposes of description of Fig. 8, it will be observed that the incline 34a will normally (during operation) face the adjacent surface of the bar member 24 and will thus have a tendency to move the calks 34 in an upward direction as respects the showing in Fig. 8 and which upward direction of course is inwardly as respects the door edge 41. However, the movement upwardly of the bar member 24 is resisted as the gauge surface 39 of said bar member 24 engages with the surface 41 of the door base 19. Thus with the forces resisting each ot her, the calks 34 can be driven directly into the base 19 of the door 1920 and there will be no relative movement inwardly of the door base 19 or upwardly as respects the showing in Fig. 8 of the drawings.

Obviously changes may be made in the form, dimensions, and the arrangements of the parts of my invention without departing from the principle thereof, the above setting forth only a preferred form of embodiment of my invention.
